Thesewing machinefurtherincludes a, frame. 'l8.which overhangs 'a portion of then-basei6. fI'he.frame 18 supports a pressure foo-t l9.which may beraisedjromthe 3.3, operative positionishown infFjig. 2,toitheinoperative position shown in"'Fig.: 6. The frame-J8,furthersupports a sewing needle 20.

"Theiramelflof thesewin machine l5 further support and carrieso; hopper2|, which isdesignedto feedthe'tipsil ii from a supply in a manhead 24of an ejectingplupger M which is held in anihoperative condition by acoil spring 124. The tip holding device is characterize -by abracket,.25 which is located at a point; spaced slightlylaterally of theend of the sewing machine base |6;and uponthe top face of theta'ble Il..Thebracketis secured in position hymeansof several screws 26 which passfreelythrough the .nerto beconvenientlyengaged uponthe tiplioldbracket25 and threadedly engage the table top H.

An arm 21. is pivotally supported upon the bracket 25 and projectsupwards and laterally thereof. The arm 21 has its bottom end engagedbetween a pair of upwardly extending lugs 28 formed on the bracket 25.

A shoulder screw 29 is engaged through the overlapped portions of thelugs 28 and the end of the arm 21 for pivotally supporting the arm uponthe bracket 2 5.

A member 30 is mounted horizontally upon the top end of the arm 21. Themember 30 is slidably but non-rotatively mounted upon the top end of thearm 21 and is adapted to move laterally of the machine l5. The member30 is disposed between the arms of a bifurcated end 3| formed upon thetop end of the arm 21. A square stud 32 is extended between the arms ofthe bifurcated end 3| and passes through an elongated slot 33 formed inthe end of the member 30. The top and bottom faces of the square stud 32are in intimate contact with the faces of the member 30 defining theslot 33. This intimate contact limits relative rotation between the stud32 and the member 3!] but permits the member to be moved laterally ofthe stud.

The member 30 supports a tip holder rod 34. The end of the tip holderrod 34 is adapted to be engaged into the longitudinal opening |3 of thetip ID as shown in Fig. 8. When the tip I is in position upon the end ofthe rod 34 the pressure foot may be urged downwards to move the tip andtip holder rod 34 downwards into a position in which the tip will be inintimate contact with 3 34 to fixedly hold the rod 34 in variousextended positions. This adjustment is provided to permit the positionof the tip l0 when in position on the end Of the tip holder 34 to beadjusted to align its passage I4 with the needle 20.

Resilient means is provided for urging the arm 7 21 and the horizontalmember 30 and the tip holder rod 34 into a normal position in which atip I ll mounted upon the end of the tip holder rod 34 will be slightlyabove the base IB of the sewing machine when the pressure foot I9 israised. This position is illustrated in Fig. 6.

The first of these resilient means is provided for urging the arm 21laterally with relation to the bracket 25. This means is characterizedby a coil spring 38 mounted in an opening 39 formed in one of the lugs28. The spring 38 and opening 39 encircle the end of the screw 29 whichrotatively supports the arm. The spring 38 has one of its ends connectedwith the bottom end of the arm 21 and its other end connected with thelug 28. This spring 38 exerts a force sufliciently great to pivot thearm 21 and the elements it carries relative to the bracket but a forceless than the force exerted. by the pressure foot l9 so that when thepressure foot 33 is moved downwards, its downward force will be capableof pivoting the arm 21 relative to the bracket 25 to engage the tip l0against the umbrella cover I resting upon the base 15 of the machine IS.

The other resilient means is characterized by an expansion spring 40which operates between the square stud 32 and the end of the slot 33 forurging the member 30 laterally outwards relative to the arm 27. Aprojection 4| extends from the end wall of the slot 33 and projects intothe open end of the spring 45 for holding the end of the spring 40 inposition in the end of the slot 33.

Means is provided for limiting pivoting of the arm 21 relative to thebracket 25. This means is characterized by a lug 42 which projects fromthe bracket 25 and which extends upwards along side of the arm 21. A setscrew 43 is threadedly engaged through the lug 42 and is adapted toengage the side of the arm 21 in the normal position of the arm shown inFig. 6.

As shown in Fig. 5 the inner faces of the arms of the bifurcated end 3|of the arm 21 converge inwardly and only touch the member at the sidesof the stud 32. This permits slight sidewise movement of the member 30relative to the arm 21, and is for the purpose of preventing the needle20 or the tip Ill from being broken in the event the needle should comedown with the passage M of the tip improperly aligned with the needle20. If this should happen the needle 20 will merely ride across thecurved face of the tip and urge the tip H], the tip holder rod 34 andthe member 30 slightly sidewise about the converging sides of the armsof the bifurcated end 3| as a pivot and pass the tip l0 by.

The operation of this form of the invention is as follows:

Assuming the machine is in the position illustrated in Fig. 2. Theneedle 20 is reciprocated and oscillated to and fro and will engagethrough the passage l4 and through the material of the cover H on eitherside of the tip H] to securely attach the tip to the cover. After thesewing operation is completed the thread is severed and the pressurefoot I9 is raised. The end of the tip holder rod 34 is then disengagedfrom the opening |3 in the tip and the spring 28 will pivot the arm 21to cause the end of the tip holder rod 34 to assume the position shownin full lines in Fig. 6. The device is now ready to receive the next tipID. the hopper 2| and is manually engaged upon the end of the tip holderrod 34 with its passage |4 directed upwardly by passing the end of therod 34 into the-opening |3 To continue the application of the tips ID tothe cover I I, the next spot on the cover to which a tip is to beapplied is brought into position beneath the pressure foot. The pressurefoot is then lowered and pivots the arm 21 about the screw 29 againstthe holding action of the spring 38 to engage the tip ID on the face ofthe cover I nd the sewing operation is repeated.

To engage new tips ||l upon the end of the tip holder rod in the normalraised position of the rod, the member 30 may be moved manuallylaterally inwards relative to the stud 32 and against the holding actionof the spring 40 as indicated by the dot and dash line 30' in 6. Thiscauses the free end of the tip holder rod 34 to be extended from beneaththe pressure foot as indicated by the dot and dash lines 34' in Fig. 6to permit the tip Hi to be more easily manually properly engaged uponthe end of the rod 34 with its passage l4 extended vertically.

In the modification of the invention illustrated in Figs. 9 and 10,provision is made for attaching the tip I0 to the cloth cover H of theum,- brella with its longitudinal opening |3 directed Another tip Ill ismanually removed from ms-rayon ra diaily'inwai'ds'to'beTengageablem'oreeasiiy with the .endaoi therib oftheumbrella frame.To'accomplisnthisthe \n'nbrefla cover I l is-disposed .upon thenoa'se "l6""of"'the"sewing"machine I 5""t0 extend lateraliy outwards" of'the'machineras 5 ."en'ds.
